* cfb_console.c |
|
* |
|
* Color Framebuffer Console driver for 8/15/16/24/32 bits per pixel. |
|
* |
|
* At the moment only the 8x16 font is tested and the font fore- and |
|
* background color is limited to black/white/gray colors. The Linux |
|
* logo can be placed in the upper left corner and additional board |
|
* information strings (that normally goes to serial port) can be drawn. |
|
* |
|
* The console driver can use a keyboard interface for character input |
|
* but this is deprecated. Only rk51 uses it. |
|
* |
|
* Character output goes to a memory-mapped video |
|
* framebuffer with little or big-endian organisation. |
|
* With environment setting 'console=serial' the console i/o can be |
|
* forced to serial port. |
|
* |
|
* The driver uses graphic specific defines/parameters/functions: |
|
* |
|
* (for SMI LynxE graphic chip) |
|
* |
|
* VIDEO_FB_LITTLE_ENDIAN - framebuffer organisation default: big endian |
|
* VIDEO_HW_RECTFILL - graphic driver supports hardware rectangle fill |
|
* VIDEO_HW_BITBLT - graphic driver supports hardware bit blt |
|
* |
|
* Console Parameters are set by graphic drivers global struct: |
|
* |
|
* VIDEO_VISIBLE_COLS - x resolution |
|
* VIDEO_VISIBLE_ROWS - y resolution |
|
* VIDEO_PIXEL_SIZE - storage size in byte per pixel |
|
* VIDEO_DATA_FORMAT - graphical data format GDF |
|
* VIDEO_FB_ADRS - start of video memory |
|
* |
|
* VIDEO_KBD_INIT_FCT - init function for keyboard |
|
* VIDEO_TSTC_FCT - keyboard_tstc function |
|
* VIDEO_GETC_FCT - keyboard_getc function |
|
* |
|
* CONFIG_VIDEO_LOGO - display Linux Logo in upper left corner. |
|
* Use CONFIG_SPLASH_SCREEN_ALIGN with |
|
* environment variable "splashpos" to place |
|
* the logo on other position. In this case |
|
* no CONSOLE_EXTRA_INFO is possible. |
|
* CONFIG_VIDEO_BMP_LOGO - use bmp_logo instead of linux_logo |
|
* CONFIG_CONSOLE_EXTRA_INFO - display additional board information |
|
* strings that normaly goes to serial |
|
* port. This define requires a board |
|
* specific function: |
|
* video_drawstring (VIDEO_INFO_X, |
|
* VIDEO_INFO_Y + i*VIDEO_FONT_HEIGHT, |
|
* info); |
|
* that fills a info buffer at i=row. |
|
* s.a: board/eltec/bab7xx. |
|
* |
|
* CONFIG_VIDEO_SW_CURSOR: - Draws a cursor after the last |
|
* character. No blinking is provided. |
|
* Uses the macros CURSOR_SET and |
|
* CURSOR_OFF. |
